Update pyproject toml and fixed dataset registry filtering

[fvera02]

Cleaned up pyproject.toml:

• Uses Hatch to define project tasks and scripts; easy to run linting, type checking, tests, docs, and benchmarks from a single toolchain instead of separate task runners
• Removed duplicate [tool.hatch.envs.docs] section
• Added pytest summary/logging options in tool.pytest.ini_options

Fixed dataset registry filtering:

• [list_datasets(family=...)] now uses [manifest_info()] for runtime manifest lookup. This ensures test patching works correctly and family/modality filters behave as expected

Verified test results in the current environment:

• [pytest -q] passes with 283 passed, 3 skipped
